Neutron and gamma spectra in delayed neutron decay of some fission products (in German)
From spring meeting of the Deutsche Physikalische Gesellschaft. Part A, nuclear physics; Heidelberg, Germany (19 Feb By use of fast radiochemical separation methods, (separation time: 24 sec), several short-lived isotopes of As, Se, Br, Te, and I were isolated from /sup 235/U fission products and identified as emitters of delayed neutrons. With the new high pressure, high resolution /sup 3/He(n,p) spectrometers, the delayed neutron spectra of /sup 85/ As (T/sub 1/2 = 2.0 sec) and /sup 87/Br (T/sub 1/2 = 55 sec) were measured along wi th the gamma spectra up to energies above the neutron binding energy. The results are discussed under the following aspects: systematics of the neutron emission probabilities, preferred population of energy levels in BETA --decay within the range of high level density, competition of neutron and gamma emission, neutron-emitting decay into excited energy states of the daughter nuclide.
